Homework and Emergencies Emergency UNIX and Linux Support Accidentally Changed File Ownership to Include a "Comment" [AIX] Post 302711085 by hicksd8 on Friday 5th of October 2012 11:19:56 AM

Yes, I agree, it's seeing # Scott from the /etc/passwd as the userid of the UID lookup from that file.

If you know the root userid password and can login as God then you should be able to change ownership of any files (single or recursive) by using a UID only, for example:

Code:
 
chown 3645 <filename>

The 3645 should appear in /etc/passwd as a valid UID of a user.

(You could change it to any UID number of your choice (not a valid user) but this may give you denied access later (which is what you've already done).

Login as God, use chown with a UID that matches up to a user in /etc/passwd.

passmgmt(1M)						  System Administration Commands					      passmgmt(1M)

NAME
passmgmt - password files management SYNOPSIS
passmgmt -a options name passmgmt -m options name passmgmt -d name DESCRIPTION
The passmgmt command updates information in the password files. This command works with both /etc/passwd and /etc/shadow. passmgmt -a adds an entry for user name to the password files. This command does not create any directory for the new user and the new login remains locked (with the string *LK* in the password field) until the passwd(1) command is executed to set the password. passmgmt -m modifies the entry for user name in the password files. The name field in the /etc/shadow entry and all the fields (except the password field) in the /etc/passwd entry can be modified by this command. Only fields entered on the command line will be modified. passmgmt -d deletes the entry for user name from the password files. It will not remove any files that the user owns on the system; they must be removed manually. passmgmt can be used only by the super-user. OPTIONS
-c comment A short description of the login, enclosed in quotes. It is limited to a maximum of 128 characters and defaults to an empty field. -e expire Specify the expiration date for a login. After this date, no user will be able to access this login. The expire option argument is a date entered using one of the date formats included in the template file /etc/datemsk. See getdate(3C). -f inactive The maximum number of days allowed between uses of a login ID before that ID is declared invalid. Normal values are posi- tive integers. A value of 0 defeats the status. -g gid GID of name. This number must range from 0 to the maximum non-negative value for the system. The default is 1. -h homedir Home directory of name. It is limited to a maximum of 256 characters and defaults to /usr/name. -K key=value Set a key=value pair. See user_attr(4), auth_attr(4), and prof_attr(4). The valid key=value pairs are defined in user_attr(4), but the "type" key is subject to the usermod(1M) and rolemod(1M) restrictions. Multiple key=value pairs may be added with multiple -K options. -k skel_dir A directory that contains skeleton information (such as .profile) that can be copied into a new user's home directory. This directory must already exist. The system provides the /etc/skel directory that can be used for this purpose. -l logname This option changes the name to logname. It is used only with the -m option. The total size of each login entry is limited to a maximum of 511 bytes in each of the password files. -o This option allows a UID to be non-unique. It is used only with the -u option. -s shell Login shell for name. It should be the full pathname of the program that will be executed when the user logs in. The maxi- mum size of shell is 256 characters. The default is for this field to be empty and to be interpreted as /usr/bin/sh. -u uid UID of the name. This number must range from 0 to the maximum non-negative value for the system. It defaults to the next available UID greater than 99. Without the -o option, it enforces the uniqueness of a UID. FILES
/etc/passwd /etc/shadow /etc/opasswd /etc/oshadow ATTRIBUTES
See attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Availability |SUNWcsu | +-----------------------------+-----------------------------+ |Interface Stability |Evolving | +-----------------------------+-----------------------------+ SEE ALSO
passwd(1), rolemod(1M), useradd(1M), userdel(1M), usermod(1M), auth_attr(4), passwd(4), prof_attr(4), shadow(4), user_attr(4), attributes(5) EXIT STATUS
The passmgmt command exits with one of the following values: 0 Success. 1 Permission denied. 2 Invalid command syntax. Usage message of the passmgmt command is displayed. 3 Invalid argument provided to option. 4 UID in use. 5 Inconsistent password files (for example, name is in the /etc/passwd file and not in the /etc/shadow file, or vice versa). 6 Unexpected failure. Password files unchanged. 7 Unexpected failure. Password file(s) missing. 8 Password file(s) busy. Try again later. 9 name does not exist (if -m or -d is specified), already exists (if -a is specified), or logname already exists (if -m -l is speci- fied). NOTES
Do not use a colon (:) or RETURN as part of an argument. It is interpreted as a field separator in the password file. The passmgmt command will be removed in a future release. Its functionality has been replaced and enhanced by useradd, userdel, and usermod. These commands are currently available. This command only modifies password definitions in the local /etc/passwd and /etc/shadow files. If a network nameservice such as NIS or NIS+ is being used to supplement the local files with additional entries, passmgmt cannot change information supplied by the network name- service.
